Get an Email's MIME into a StringBuilder

Demonstrates the Chilkat Email.GetMimeSb method, which returns the email as MIME text (header, body or bodies, related items, and all attachments) by appending it to a StringBuilder object. This example builds a message and appends its MIME to a StringBuilder.

Background: This is a StringBuilder-based alternative to GetMime, which returns a plain string. Writing into a StringBuilder is more efficient when the MIME is large or when you intend to further manipulate it — searching, replacing, or accumulating additional text — without creating many intermediate string copies.
